Bootable CD

Can anyone help me with detailed instructions for creating a bootable CD-ROM?
I need one each for DOS, Win95, Win98, NT (server & workstation), 2000 (server & workstation) & XP.
These will be diagnostic / utility disks.
I subscribe to a lot of lists, I seem to remember an article about creating bootable diagnostic CDs for DOS and / or Windows in the last 12 months, but I can't find it.
I'm technically literate, so I don't need every last tiny "now push this button" instruction, but I do need the detailed course.
